Definitions
- This invention relates to pipe couplings and more particularly, it relates to a pipe lap joint especially adapted for use in vehicle exhaust systems.
- a pipe coupling with a lap joint for exhaust systems with high pull-apart strength and good fluid sealing is also disclosed in the Cassel U.S. Pat. No. 4,056,273 granted Nov. 1, 1977.
- the coupling disclosed in this patent comprises a wide band clamp with a sealing ring disposed around the inner pipe and having an outer diameter about the same as that of the outer pipe. the wide band clamp covers the sealing ring and the end of the outer pipe, spanning the junction therebetween, and is stretched into tight engagement against the sealing ring and the outer pipe.
- the coupling disclosed in this patent comprises an open sleeve which is stretched around the pipes.
- the open sleeve comprises a roundish sector and a channel-shaped sector comprising a pair of sidewalls extending radially outwardly from the roundish sector.
- Force applying means are connected with the sidewalls to draw them together so that the roundish sector of the sleeve is stretched over the pipes.
- a pipe coupling of the lap type in which a fluid tight seal is provided with a clamping sleeve or band which engages the outer pipe only, i.e. which does not span the outer pipe and inner pipe.
- the fluid seal is achieved by using an outer pipe with a collapsible sealing ring or zone at its free end which is collapsed into sealing engagement with the inner pipe by tightening a clamping band thereon.
- a pipe lap joint of this type is disclosed in the Wagner et al U.S. Pat. No. 4,113,289 granted Sept. 12, 1978.
- the collapsible sealing zone in the Wagner et al patent comprises several sets of slots which are disposed circumferentially around the end of the outer pipe. In each set of slots, there is an open slot which extends inwardly from the end of the pipe and an adjacent closed slot, i.e. it does not extend to the end of the pipe.
- One difficulty with this sealing zone is that the slot structure exhibits a relatively high resistance to collapsing and accommodates a relatively small amount of reduction in the circumference of the pipe at each set of slots.
- a lap joint of the type using a collapsible sealing zone is also disclosed in the aformentioned Cassel U.S. Pat. No.
- a collapsible sealing ring forms an extension of the outer pipe but is separate therefrom.
- This sealing ring is split so as to form a tongue on each free end with the tongues having complementary ramp surfaces in engagement with each other and which slide relative to each other when the ring is contracted or collapsed.
- This sealing ring provides a good seal but the structure is not adapted to a sealing ring which is integral with the pipe end.
- One difficulty is that it requires a shearing operation which results in bending in the region of the shear line and then requires reforming the pipe end.
- a general object of this invention is to overcome certain disadvantages of the prior art and to provide an improved pipe lap joint.
- an improved pipe lap joint which exhibits high pull apart strength, good fluid sealing and which is economical to manufacture.
- an improved pipe lap joint in which the overlap region of the outside pipe comprises a collapsible sealing zone with at least one pair of intersecting end-to-end slots which afford relief for circumferential contraction with of sealing zone.
- a clamping band is disposed around the outside pipe and covers the inboard slot. Tightening means are provided for clamping the band around the outside pipe to clamp the pipes together and collapse the sealing zone of the outer pipe into close fitting engagement with the inner pipe to cause sealing engagement of the outer pipe with the inner pipe and with the band.
- the intersecting slots comprise an outboard slot with sidewalls extending inwardly from the end of the outside pipe and terminating in a transverse inner end wall within the overlap region, and an inboard slot circumferentially offset from the outboard slot with sidewalls extending axially inwardly from an outer end wall, the adjacent sidewalls of the slots being in substantial alignment with each other and the end walls being in substantial alignment with each other.
- FIG. 1 is an exploded view of the lap joint of this invention showing the parts before they are assembled;
- FIG. 2 shows the lap joint of this invention with the parts assembled and after the joint has been tightened
- FIG. 3 is a view taken on lines 3--3 of FIG. 2;
- FIG. 4 is a view taken on lines 4--4 of FIG. 2;
- FIG. 5 shows the face of a punch for forming slots in one of the pipes.
- the pipe joint 10 of this invention comprises, in general, inside and outside pipes 12 and 14, respectively, in a telescoping relationship with a band clamp 16 for holding the pipe together.
- the outside pipe 14 has a lap portion which extends over the inside pipe 12 to provide an overlap region 18 of the pipes.
- a radially collapsible sealing zone 22 is provided on the outise pipe 14 in the overlap region 18. The collapsible sealing zone 22 will be described in detail presently.
- the sealing zone 22 comprises a ring shaped portion of the free end of the outside pipe 14. It is adapted to be contracted or collapsed in the radial direction by the clamp 16 so that the sealing zone 22 is in close fitting engagement with the inside pipe 12.
- the sealing zone 22 is provided with a pair of intersecting slots 24 disposed in offset end-to-end relationship. In the illustrative embodiment, only a single pair of intersecting slots is used. However, in certain embodiments it may be desirable to use two pairs of slots, with one pair disposed diametrically opposite the other pair.
- the pair of intersecting slots 24 is shown in FIG. 1 before the sealing zone 22 is collapsed, i.e. before the diameter of the sealing zone is reduced by the force of the clamp 16.
- the pair of intersecting slots 24 comprises an outboard slot 26 is bounded by a pair of sidewalls 32 and 34 extending inwardly from the end of the outside pipe and terminating in a transverse inner end wall 36 within the overlap region 18.
- the sidewalls 32 and 34 are substantially parallel to each other and to the axis of the pipe 14 whereas the end wall 36 extends obliquely of the sidewalls at a small angle from perpendicularity.
- the inboard slot 38 is bounded by a pair of sidewalls 42 and 44 extending axially inwardly from an outer end wall 46 thereof to an inner end wall 48.
- the end wall 36 of slot 26 and the end wall 46 of slot 38 lie on substantially the same line, i.e. they are in substantial alignment with each other. Also, the adjacent sidewalls, namely sidewall 34 and sidewall 42 are in substantial alignment with each other.
- the slot 26 intersects the slot 38 between the corner formed by end wall 36 and sidewall 42 and the corner formed by end wall 46 and sidewall 34. These corners are detached from each other, at least over a portion of the pipe wall thickness as a result of the slot forming operation which will be described presently.
- the pair of intersecting slots 24 is formed in the end of pipe 14 by a punching operation.
- the inside pipe 12 has a nominal outside diameter of one and three-fourths inches and the end of the outer pipe 14 is expanded to form a loose fit over the inside pipe.
- the wall thickness of the pipes is 0.048 inches.
- the punch for forming the pair of slots 24 coacts with a horn die inside the pipe end and has a shape corresponding to the slots as shown in FIG. 1.
- the punch face is shown in outline form in FIG. 5.
- the punch is constructed as two separate punch segments, one for each of the slots, and the segments are mounted for movement in unison to punch the slots in a single stroke.
- the die is constructed to mate with the punch in accordance with conventional practice. As a result, the punching operation causes the punch-out material to break away from the pipe wall around the periphery of the slots so that the slot dimensions are slightly larger on the inside diameter than on the outside diameter. Since the die segments have point contact at the point P, the corners of the slots 26 and 38 will be spaced apart, at least on the inside diameter of the pipe and the slots thereby intersect and are open to each other.
- the clamp 16 comprises a clamping band 52 which is disposed around the outer pipe 14 over the sealing zone 22.
- the clamping band 52 for sealing purposes, must cover the inboard slot 38 and cover the juncture of the end walls 36 and 46.
- the clamping band 52 is provided with a tightening means 54.
- the clamping band 52 is, for the most part, circular or roundish in cross-section. It has a roundish sector 56 adapted to fit around the sealing zone 22 on pipe 14 and a channel-shaped sector 58 which comprises a pair of sidewalls 62 and 64 extending radially outwardly from the roundish sector.
- the clamping band 52 is made of a single piece of sheet metal and each free end thereof is folded back on itself to form a double layer.
- the sidewalls 62 and 64 are of double thickness and terminate at their outer ends in respective loops or bights 66 and 68.
- the bights 66 and 68 serve as retaining members for holding the sidewalls in place when the tightening means 54 is tightened, as will be described subsequently.
- the clamping band 52 is tightened around the pipe 14 by the tightening means 54.
- the tightening means comprises a reaction member or spline 72 which is disposed within the channel-shaped sector 58 and which is adapted to seat upon the outer surface of the sealing zone 22 of pipe 14.
- the spline has an inner surface of arcuate configuration conforming to the pipe 14.
- the spline 72 is provided with a pair of oppositely facing concave surfaces 74 and 76.
- the tightening means includes a bolt 78 and a nut 82. It also includes a spacer 84 disposed outside the sidewall 64 and having a convex surface which is opposite the concave surface 74 of the spline 72.
- the bolt 78 has a head 81 with a convex surface which is disposed outside the sidewall 64 opposite the concave surface 76 on the spline 72.
- the bolt extends through holes in the sidewalls 74 and 76, the spline 72 and the spacer 84.
- This tightening action of the clamp 16 exerts sufficient force on the sealing zone 22 to crush or collapse the sealing zone by partially closing the intersecting slots 24 with sliding engagement of the end walls 36 and 46 with each other.
- the sealing zone 22 is radially collapsed into sealing engagement with the inside pipe 12 and the clamp 16 is in sealing engagement with the sealing zone over the inboard slot 38.
- the engagement of the end walls 36 and 46 of the slots closes the path between the slots so that a good fluid seal of the joint is assured.
